friction brake. The disc 26 is mounted on screw 23 between the roller and the head of the screw and the braking eifect of the disc can be adjusted by screwing 23 inwardly or outwardly. It is desirable for the roller II to be rotatable on the screw 23. However, in order to check the closing action of the screen door said roller II can not rotate freely but considerable braking action must be applied thereto by the disc 26 so that it will rotate to a slight extent and then only upon substantial impact as a result of engagement therewith of roller I4.

Said roller I4 is carried by bracket I3 having a securing iiange 28 and depending ears 33. IThe bracket is suitably iixed to the frame I of the door by securing screws 3l which have location in slots 32 whereby the bracket can be adjusted vertically for adjusting the contact of roller I4 with roller II to securethe desired checking of the screen door when the rollers engage. 'Ihe depending ears 30 are apertured for receivingthe screw 33, Figure 3, which at its right hand end is threaded to the bracket with its projecting end having threaded thereto the wing nut 34 for The roller I4 is journalled on the screw 33 by the headed sleeve 35 and the washer 36 is provided -for applying variable tension to the roller whereby said rwasher regulates the braking effect on roller I4 in much the same manner as disc 26 regulates the braking eiTect of roller II. The screw 33 carries at its left end the coil spring 3l vwhich is confined between the head of the screw and the collar 38, said collar having free contact with the washer 36 and applying thereto the tension exerted by coil spring 31. The ear 33 -is apertured for receiving vthe collar 38 which is thus held by the bracket I 3 and centered for journalling the screw 33.

'."`InI application of the present device the bracket I0 is suitably secured to jamb I2, as illustrated in Figure 1, at a point approximately `r'ndway 'of the upper half of `the door. 'bracket I3 is secured to the frame I5 of the door 'and the vertical positioning of the bracket is such 'that the rubber roller I 4 will contact rubber roller 'II' as the screen door closes against the door The ja'mb. To facilitate the proper positioning of 'bracket I3 the flange 28 of said bracket is provided with slots 32. The positioning of rubber roller I4 with respect to roller II is somewhat `the rollers for silencing and cushioning the jar as the door closes it is only necessary to loosen up on screws 3| and adjust the bracket until proper contact results.

' For proper closing action of the door and oper- 'ation of the vparts to prevent rebound it is also necessary that the disc 26 and washer 3B have adequate tension applied thereto for braking the rollers. By adjustment of screw 23 the proper braking eiect can be obtained for the roller lI `-and the braking action on roller 'I4 can be adjusted by manipulation of screw 33. When roller I4 passes over the high point with respect to roller a 4 II, the rollers should rotate on their respective axes, thereby facilitating the final closing movement of the door. When the parts assume the position as shown in Figure 4, the screen door is completely closed and it will be observed that the same is held closed by the contact which roller I4 has with roller II. This may be described "as a locking position for roller I4 since the same beyond dead center as regards roller I I. This action which the rollers have with each other not only releasably holds the door closed but prevents rebound of the door.

The action of the present device in preventing rebound is very desirable and comprises one of the important functions of the device, the function resulting from coaction of the same parts which also cushion the closing of the door and silence the closing action. When roller I4 passes over the high point of roller I I the resilient material of the rollers is compressed which results in the rotative movement of the rollers as described and cushioning of the closing action of the door. When the-rollers assume the position as shown in Figure 4 they are no longer compressed but their peripheries are fully y'expanded to original position. Since considerable force is required to compress the material of the rollers the door is held closed and any rebound action is absorbed by the rollers.

The invention is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings as various forms of the device will of course be apparent to those skilled in the art without departing fromv the spirit of the invention or the scope of the claims. f

What is claimed is:

1. In a door check and silencer for a door jamb and a door hingedly mounted for openingfand closing movements therewith, in combination, a `bracket lxedly secured to the jamb, a roller journalled by the bracket, adjustable means for tensioning the roller to prevent free rotation, a second bracket providing spaced depending ears. a roller located between said ears and journalled by a screw, said second bracket being xedly secured to the door ina position whereby the rollers contact each other as the door closes and have a compressing action to check the closing of the door and to silence the same, said screw having threaded engagement with one ear and projecting beyond both ears, resilient means retained by one of the projecting ends of the screw for applying tension to the said roller journalled betweenthe ears, and a wing nut threaded to the other projecting end of said screw for locking the screw in adjusted position.

2. In a door check and silencer for a door jamb and a door hingedly mounted for opening and closing movements therewith, in combination, a bracket for securement to the door jarnb having a center portion, a shaft adjustably secured to the center portion and projecting outwardly therefrom, a resilient roller journalled by said shaft, a second bracket providing spaced depending ears, a roller located between said ears and journalled by` a screw, said second bracket being xedly secured to the door in a position whereby the rollers contact eachother as the door closes and have a compressing action to check the closing of the doorand to silence the same, said screw having threaded engagement with one and projecting beyond both ears, resilient means retained by one of the projecting ends of the screw for applying tension tothe said roller journalled 5 between the ears, and a wing nut threaded to the other projecting end of said screw for locking the screw in adjusted position.
